The total number of species in an area is termed? a.) species richness b.) species abundance c.) species evenness d.) genetic diversity

Has to be B. That is because A and C are "stupid" answers (as my teacher calls it" and D refers to the amount of types of species not altogether.

Deltas are similar to alluvial fans in shape, but are deposited in a different environment. Sediments that form deltas are transported in continuous flowing water. Delta deposits are found at the mouths of streams or rivers as they empty into lakes and oceans also River channels cross delta and alluvial fan deposits. Hope I helped a bit
